Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of disposable internal fistula paracentesis trocar.Be that a kind of hemodialysis patients that is used for implements to set up before the hemodialysis instrument that patient's vascular access carries out the internal fistula puncture.
Background technology
Hemodialysis is one of main kidney replacement therapy method of renal failure patient.When carrying out hemodialysis, the doctor at first sets up patient's vascular access, will dash good dialyser and disposable blood vessel then in advance and be connected to the patient's blood vessel path, sets up extracorporeal circulation and begins hemodialysis.
Original disposable internal fistula puncture needle mainly by: draw point and plastic tube connect to form.With normal saline the internal fistula puncture needle is dashed in advance earlier before the puncture.Artery and vein and fixing then punctures respectively.
The defective that said structure exists is: when 1, using original disposable internal fistula puncture needle during puncture, wear out blood vessel easily and cause puncture failure.2, hemodialysis patients will move a lower arms unavoidably in the 4-5 that carries out hemodialysis hour, very easily caused being punctured blood vessel by sharp draw point and caused local swelling and the subcutaneous hyperemia of large tracts of land.3, draw point hardness Da Yi causes oozing of blood.4, the steel syringe needle is prone to touch blood vessel wall and causes the artery blood flow sucking-off not smooth.5, original internal fistula puncture needle is difficult for fixing, and puncture needle slippage incident takes place easily.6, influence the service life of patient's artery and vein internal fistula.7, the patient comfort is poor.
Summary of the invention
The purpose of this utility model provides a kind of disposable internal fistula paracentesis trocar, is made up of puncture draw point and sleeve pipe, and the puncture draw point is hollow, and overall diameter is 16G (1.6mm) or 15G (1.7mm), and tail end is draw point joint and draw point connector cover; The sleeve pipe head end is that a segment length is that soft needle tubing is used in the indwelling of the high texture with certain crushing resistance of 26mm, is provided with 4 symmetric apertures at soft needle tubing head end, soft needle tubing tail end adapter sleeve bobbin hard seat; Trocar hard seat connects flexible pipe, the head end of hose connection three-way interface seat, and the logical tail end of the side of three-way interface seat connects flexible catheter; The flexible catheter tail end is provided with spiral port; And be with the conduit medicated cap, and on flexible catheter, being with hemostatic clamp, the straight-through tail end of three-way interface seat connects rubber closure; The puncture draw point penetrates rubber closure and gets into sleeve pipe, also is provided with detachable needle sheath lid at the sleeve pipe head end.The draw point connector cover can take off, and can connect the syringe blood drawing in the time of necessary and use.
Soft needle tubing is connected with trocar hard seat through fluid sealant, and trocar hard seat connects the transparent silica gel flexible pipe through fluid sealant, and flexible pipe connects the three-way interface seat through fluid sealant, and hollow puncture draw point and syringe joint adopt injection moulding to fix.
The disposable internal fistula paracentesis trocar that this utility model provides is a kind of safe, comfortable internal fistula paracentesis trocar; Mainly solve the problem that is prone to cause internal fistula swollen blood vessels and patient comfort's difference that original disposable internal fistula puncture needle (draw point) exists, thereby prolong the service life of the artery and vein internal fistula of dialysis patient.This internal fistula paracentesis trocar can be optimized care program, can make apparatus reach optimum efficiency after the use.(1) this trocar has aperture on the flexible catheter top, can in the shortest time, see blood back rapidly, helps to judge early that being punctured with denys in the intravasation; Owing to adopted flexible catheter, and used needle point to return the method for sending pipe in the flexible catheter again, thereby avoided puncture excessive (puncturing blood vessel) and the puncture failure of appearance, the raising puncture success rate.(2) flexible catheter of this utility model design is floating state in blood vessel, has reduced the compressing to blood vessel, thereby has avoided obstructed to the bloody path that the compressing of blood vessel causes because of conventional steel, has improved the flow and the quality of hemodialysis greatly.(3) because flexible catheter is floating state in blood vessel, avoided conventional steel to the long-time stimulation of blood vessel and possible tunica intima damage, reduced the incidence rate of phlebitis and thrombosis, reduce the generation of complication.(4) because draw point hardness is big and the histocompatibility difference is prone to cause oozing of blood, and the internal fistula paracentesis trocar has adopted flexible catheter, thereby has avoided occurring oozing of blood.(6) the internal fistula paracentesis trocar easy fixation that provides avoids taking place puncture needle slippage incident.(7) service life of prolongation internal fistula blood vessel.The internal fistula blood vessel is vital to dialysis patient, must protect to full capacity.Owing to adopted the internal fistula paracentesis trocar of band flexible catheter, significantly reduced the generation of various complication, thereby prolonged the service life of patient's internal fistula blood vessel to greatest extent.(8) improved patient's comfort level greatly.In dialysis procedure, patient's a hands must be motionless at 4-5 hour internal fixation in the past.Careless slightly or mobilely just possibly puncture blood vessel, cause the subcutaneous hyperemia of hemodialysis interruption and swelling and large tracts of land.Adopted the internal fistula puncture needle of band flexible catheter, had only flexible catheter to be trapped in the blood vessel, thereby avoided puncturing blood vessel and guaranteed carrying out smoothly of hemodialysis.Patient's hands also can suitably move, and is not only safe but also comfortable.This utility model sleeve pipe is disposable use, prevents cross infection, and wound is little.This utility model is reasonable in design, and is simple in structure, easy to use, and easy operating is safe and reliable, realizes the bottom line wound, and less patient suffering is little, meets the requirement of modern medicine progress.
